1 Claim.

This invention relates to hydrants connectable in a water supply lineand the principal feature and object of the inventionis to provide ahydrant so constructed as to permit water in the hydrant, upon closingthe valve, to automatically drain from the hydrant and thus preventfreezing.

The main object of the invention is not only to prevent freezing but toprevent a cross connection between the waste outlet and the water supplywhereby ground water could be syphoned through the waste opening duringperiods of operation and polluting the water supply.

A further object of the invention is to prevent ground water beingsyphoned through the waste opening during periods of operation and thuspolluting the water in the supply conduit.

By the arrangement and relationship of parts as hereinafter more fullydescribed water remaining in the hydrant upon closing the valveaccumulates in a chamber below the frost line and is thereforeparticularly adapted for use in the North and South Frigid and TemperateZones.

A hydrant embodying my invention is shown in the accompanying drawing inwhich- Fig. 1 is a vertical section of the hydrant.

Fig. 2 is a vertical section showing a different form of chamber intowhich the water in the discharge line may accumulate. y

Fig. 3 is another form of drainage chamber having the same function asthat shown in Fig, 1.

As will be understood more clearly from Fig. l a water main is indicatedat I and lies substantially in a horizontal plane. To the water main isconnected an elbow 2 having a threaded end to receive the threaded endof the water main I and the opposite end 3 of the elbow is positioned toreceive the threaded end of a verticaltubular element 4 threaded toreceive a tube 5 which extends to above the ground level indicated bydotted lines 6.

The tubular element 4 is provided with a valve seat 'I and a valve 8 isprovided with a stem 9 which extends to above the ground surface. On theupper end of the tube 5 is a plate I9 apertured to receive the same anda plate II is secured to the plate I and seats on the upper end of thetube 5. At the upper end of the stem 9 is a knob I2 by means of whichthe stem 9 may be rotated. Said stem 9 is provided with a threadedaperture above the valve seat I to receive an enlarged threaded portionon the stem 9 and on the lower portion of the stem 9 are preferably twocupped washers I4 and I5 to prevent water accumulating in the tubularelement 4 and the tube 5. The lower end of the tubular member 4 has atubular threaded portion I6 on one side to receive one end of the elbowI'I the opposite end of which is threaded to receive a nozzle I8 and onthe vertical end of the elbow II is a chambered member I9 apertured atits lower end to receive the nozzle which is provided with a flange asindicated at 20.

The nozzle has a conical end Aportion 2| on vwhich is seated a drainageelement 22 having a chamber 23 opening to the horizontal passageways 24just above the upper end of the nozzle 2I.

By this arrangement when' the valve 8 is closed, subsequent to use ofthe hydrant,v any water remaining in the tube 25 may drain back into thechambered element IS positioned in the earth below the frost line.

The upper end of the chamber I9 has a hublike extension 26 internallythreaded to receive the lower threaded end of, the vertically positionedtube 2'I and the upp'erend of the tube 2I is likewise threaded in arecess in the lower end of the chambered member 28. The chambered member28 has the bottom wall 29 centrally threaded to receive the upperthreaded end of the tube 25. y y

The plate I0 at the upper end of the tube 5 extends over the upper endof the chambered member 28 and is secured thereto by the screws 30and3l. The chambered member further has a threaded aperture in the sidewall to receive the threaded end of the discharge nozzle 32.

In Fig. 2 is shown a different form of drainage element which includes achamber #9a correspending to the chamber I9 shown in Fig. 1 and has thesame function as that shown in Fig. 1. The drainage element 22a differssomewhat from that shown at 22 in Fig. 1 but has the same function asthe element 22 in that the apertures 24a are upwardly inclined inrespect to the horizontal and the member 22a has a Venturi-like chamber33 and the apertures 24a open to the chamber 33 just above therestricted area 34 of the chamber.

The upper end of the chambered member I9a has a hub-like extension toreceive the tube 21a in which is the tube 25a having the same functionas the tube 25 shown in Fig. 1. The lower end of the Venturi tube 22a isthreaded to engage the threaded end of a fitting 20a corresponding :innfunction to that of the tting 2i! shown in In Fig. 3 another form ofventuri is shown in which the chambered member I9b corresponds to thatshown at I9 in Fig. 1 and a tube 40 is threaded in the upper end of thechambered member I9b and a tube 4I is provided within the tube 40 andhas the same function as the tube 25 of Fig. 1. The Venturi element 42in Fig. 3 differs from the venturi 22 of Fig. 1 orV 22a of Fig. 2 inthat it has a central chamber 43 having openings 44 therein which havethe same function as the apertures 24 in the member 22 as shown in Fig.1, namely, to permit ow of water: remaining in the tube 4l upon theclosing of 'the-main valve corresponding to the valve shown at 8 inFig. 1. The tube 21 has an opening 45 therein above the ground surfacewhich permits air to flow into the tube 21 asY the water level in thereservoir I9 falls or from the tube 21 Vas the waterlevellrises; Thisar.-

rangement prevents a waste of-'water-andpre vents a vacuum occurring inthe chamber I8, 19a

4The member 20a has a central longitudinal aperture of cylindrical formand thus differs from that shown at 21 in Fig. 1. In Fig. 3 atube 20cisthreaded for a` distance from its end and is inserted intov althreaded aperture in thevbottom of the chambered'elementlb and a-nut 20dis threaded on the tube 20c and engagesthe bottom -of thechamberedmember |917. A gasket 20ev is providedA between the nutl andthe bottom of the chambered element 1 i90.

With either of Vthev forms off the invention shown closing of the mainvalve 8-permits-Water in the l conduits'v25, 25ct. or- 4I to VdrainVback into thechambered members 19,190., or I9b of the respectiveforms-of 1the-invention which,as here- `inbefore stated,` arepositionedin the earthr below thefrost'fline. The-device is Aparticularly usefulinthe watering. of'lawns.

One of the outstanding requirements fori lowering, lthe maintenancecosts of hydrant .operation is that all working parts be yaccessible forVrepairs at at point above Lthe Aground level.

Itis. believed A'obvious from the foregoingdeiscriptionl that thevarious `objectsand features ofthe invention are attainedirrespective-of: the form of: the drainage members 2222ar or 40.
